Well, the main reason is because of the Programming language, UserRPL, I can not use it, I will not spend any Second around with it.
I need a Calculator that also supports BASIC language.
Well, I will think about it for several days.

Or You may like to have a look on the HP-Prime - fantastic calculator, up to date technology, fast, unit conversions as required, powerful high level structured programming language similar to PASCAL (and to BASIC to some extent, but no GOTO instructions here, which is a goood thing...), algebraic and RPN entry modes, and much more!

However the WP-34S is an excellent programmable RPN super calculator that also includes units conversion.

And it is a free open project, so in the event You may like to build one instead of buying it ready prepared, have a look to the author's site:
